I have tryed lots of presets but same problem anywhere , when I play the guitar and do riffs like Palm mute and than "free note" , Palm mute , "free note" and so on  , the "free note" volume is normal , and palm mute sounds like 30% volume , and , I really don't know , how to fix it , I searched on lots of forums but nobody has my problem . If anybody got any suggestions , please let me know . (sorry for my bad english) . Thank you !
